再來看一下AURALiC VEGA比較特別的功能

原廠的說明書雖然是英文版的，不過只要略懂英文，很容易就看得懂的，所有用得到的資訊大概都寫在裡面了

除了專用的遙控器外，這顆選鈕是可以按下後進入設定選單的


選單畫面，這裡就不一一介紹了，只介紹VEGA比較特別之處


首先是Filter濾波的模式可選，在PCM的解碼格式，有4種可以選擇，但DSD的格式就會只會有兩種濾波模式，主要是因為一般的數位濾波反而會讓DSD頻寬的優點被抹殺，因此只設制兩個對極高頻頻段進行濾波

PCM 解碼下的4種濾波
1. MODE 1
MODE 1 offers best measurement performance with flat frequency response well extended to treble. This mode has very small in-band ripple and best stop-band
attenuation performance. MODE 1 is best for the playback of orchestral music.
2. MODE 2
MODE 2 exhibits a gentler roll-off curve of frequencies; it maintains great in-band, stop-band performance while trades off small attenuation at treble. MODE 2 is best for the playback of light jazz, chamber music and piano solo.
3. MODE 3
MODE 3 is designed to minimize the 'pre-ringing' and 'echo' effects. As a result, this mode sounds very smooth. However, due to the slow roll-off at high fre-uency, it may lose some details in treble for certain kinds of music. MODE 3 is best for vocal, jazz and pop music.
4. MODE 4 (Default)
All filters in this mode are designed to optimize the subjective listening experi-ence at maximum. By using minimum phase design, there is no 'pre-ringing' effect in this mode, the 'echo' effect is also been reduced as much as possible. MODE 4 is the 'all-best' option for music enjoyment.

DSD 解碼下的2種濾波
1. MODE 5
This mode uses higher corner frequency to maintain the flat frequency response well extended to ultrasonic.
2. MODE 6 (Default)
This mode uses lower corner frequency to eliminate as much as possible the ultrasonic noise which is inherent of DSD stream.


VEGA有一個非常少見的功能，就是時鐘的設定，共有4種模式：AUTO, COARSE, FINE, EXACT
一般情況是設定在AUTO(自動)，聲音品質與時鐘鎖定的穩定度取得平衡點


VEGA的資訊顯示功能有個很特別的地方，就是會出現使用時數，這個相當有趣，主要用途是讓用家瞭解使用的時數、預估一下熟化的時間，但另一方面，這就跟汽車的里程數一樣，若將來要出售，可以很清楚的得到機器已經聽了多久時間
